Lateral G Sensor Signal

STEP CHEEK SHEET

Step Check Yes No
1 CHECK SUBARU SELECT MONITOR.  Is the Subaru Select Monitor available? Go to step 5.  Go to step 2. 
2 CHECK YAW RATE & LATERAL G SENSOR. 
  1. Move the vehicle to a flat location.
  2. Turn the ignition switch to OFF.
  3. Connect the connector to yaw rate & lateral G sensor.
  4. Turn the ignition switch to ON.
  5. Measure the voltage between yaw rate & lateral G sensor connector terminals when it is horizontal.

Connector & terminal 
(B230) No. 5 (+) - No. 6 (-) 		 Is the voltage 2.3 V - 2.7 V? Go to step 3  . Replace the yaw rate & lateral G sensor.
3 CHECK YAW RATE & LATERAL G SENSOR. 
  1. Remove the yaw rate & lateral G sensor from vehicle.
  2. Measure the voltage between yaw rate & lateral G sensor connector terminals when it is inclined right to 90°.

Connector & terminal 
(B230) No. 5 (+) - No. 6 (-) 
NOTE: When the yaw rate & lateral G sensor is moved with its power supply on, DTC of yaw rate & lateral G sensor may be recorded.
 Is the voltage 3.3 V - 3.7 V? Go to step 4  . Replace the yaw rate & lateral G sensor.
4 CHECK YAW RATE & LATERAL G SENSOR. 
Measure the voltage between yaw rate & lateral G sensor connector terminals when it is inclined left to 90°.
Connector & terminal 
(B230) No. 5 (+) - No. 6 (-) 
NOTE: When the yaw rate & lateral G sensor is moved with its power supply on, DTC of yaw rate & lateral G sensor may be recorded.
 Is the voltage 1.3 V - 1.7 V? Yaw rate & lateral G sensor is normal. Replace the yaw rate & lateral G sensor.
5 CHECK YAW RATE & LATERAL G SENSOR. 
  1. Turn the ignition switch to OFF.
  2. Connect the Subaru Select Monitor connector to data link connector.
  3. Turn the ignition switch to ON.
  4. Turn the Subaru Select Monitor into {Current Data Display & Save} mode.
  5. Set the display in {Current Data Display & Save} mode.
  6. Read the yaw rate & lateral G sensor output voltage when vehicle is in horizontal position.
NOTE: When the yaw rate & lateral G sensor is moved with its power supply on, DTC of yaw rate & lateral G sensor may be recorded.
 Is the voltage 2.3 V - 2.7 V? Go to step 6.  Replace the yaw rate & lateral G sensor.
6 CHECK YAW RATE & LATERAL G SENSOR. 
  1. Remove the console box.
  2. Remove the yaw rate & lateral G sensor from vehicle. (Do not disconnect connector.)
  3. Read the Subaru Select Monitor display when yaw rate & lateral G sensor is inclined right to 90°.
NOTE: When the yaw rate & lateral G sensor is moved with its power supply on, DTC of yaw rate & lateral G sensor may be recorded.
 Is the voltage 3.3 V - 3.7 V? Go to step 7.  Replace the yaw rate & lateral G sensor.
7 CHECK YAW RATE & LATERAL G SENSOR. 
Read the Subaru Select Monitor display when yaw rate & lateral G sensor is inclined left to 90°.
NOTE: When the yaw rate & lateral G sensor is moved with its power supply on, DTC of yaw rate & lateral G sensor may be recorded.
 Is the voltage 1.3 V - 1.7 V? Yaw rate & lateral G sensor is normal. Replace the yaw rate & lateral G sensor.
